Nvidia has taken the wraps of its MobileMedia platform for Windows Mobile 5.0-based devices at Taiwan's big Computex trade show, promising to bring high-quality digital TV and video, 3D graphics, and high fidelity audio to PDAs and smartphones. At the heart of the MobileMedia platform is Nvidia's GeForce 5500 chip, which supposedly delivers "console-class 3D gaming," although they convienently don't specify which console -- we're guessing it falls somewhere below an Xbox 360 but above a Sega Genesis. As it turns out, we've actually already seen a couple of the smartphones based on the Nvidia platform, although no one was spilling deets at the time. Modeo's DVB-H smartphone (seen here) is just one of the devices already announced that has Nvidia tech on the inside, as is Samsung's i310 smartphone, as well as an unnamed device from ReignCom. Nvidia also announced that they've hooked up with Intel and Freescale to develop reference designs for Windows Mobile 5.0 devices currently in development that should be unveiled later this year.
